AirAsia X is investigating the incident of one of its Kuala Lumpur-bound flight being forced to return to Perth Airport due to a 'technical reason'.

In a statement, the airline said that the safety of its guests and crew is of utmost importance to them.

“We are currently conducting an investigation into the cause of the incident together with our engine manufacturer Rolls-Royce.

“We are also cooperating fully with the local aviation authorities,” it said in a statement today.

It also said that AirAsia Group has always strictly followed the maintenance programme prescribed by its manufacturers.

“We have also complied with all regulations and requirements as set forth by every country where the airline operates, including Australia.

“In Australia, AirAsia Group has also regularly passed safety and security audits conducted by the local aviation authorities. AirAsia Group has also initiated the process of undergoing voluntary IATA Operational Safety Audit (IOSA) auditing for all airlines within the group, including AirAsia X Malaysia, AirAsia X Indonesia and AirAsia Indonesia, with AirAsia X Malaysia receiving two IOSA audit certificates in 2015 and 2016,” it added.

The AirAsia X flight D7237 with 359 people on board was bound for Kuala Lumpur from Perth but returned to Perth Airport due to a 'technical reason'.

Many news reports said that the flight was shaking "like a washing machine" during the incident.

Commenting on the AirAsia X flight, Transport Minister Datuk Seri Liow Tiong Lai had said that it was a normal procedure for a flight to turn back due to technical issue.
